Hill Air Force Base officials say an F-16 jettisoned two 500-pound bombs and two fuel tanks on the base just before making an emergency landing.

Col. Scott J. Zobrist says the pilot ran into trouble after taking off Thursday afternoon and had to return to the base about 30 miles north of Salt Lake City.

He says the pilot had to drop the munitions and tanks to lighten the jet's load.

Zobrist says it appears one bomb hit an empty tin shack on base. He says there are no injuries and the plane landed safely.

Zobrist says the two fuel tanks are accounted for and the incident is contained to the base.

Emergency teams are looking to make sure there are no munitions left that could explode.
